Geochemistry of the hydrogeological reserve of Mérida, Yucatán, Mexico
Hydrochemical data are presented to describe the process that modifies the groundwater quality in northwest Yucatán. Solution of almost pure carbonate rocks, conservative mixing with seawater and ionic interchange in clayey limestone of middle Eocene are found. Groundwater flow is from the central z...

| Sumario: | Hydrochemical data are presented to describe the process that modifies the groundwater quality in northwest Yucatán. Solution of almost pure carbonate rocks, conservative mixing with seawater and ionic interchange in clayey limestone of middle Eocene are found. Groundwater flow is from the central zone of the study area outward. New observations confirm earlier studies on proposed conservation measures in the area. Brackish water is found several kilometers inland. Salinity increase is due to saltwater upconing in relatively deep wells or by the concentration of pumping. |
